Final answer:
Excess yellow bile in Galen's humoral theory causes a choleric temperament, characterized by passionate, ambitious, and bold behavior.
Step-by-step explanation:
According to Galen's humoral theory of temperament, which is based on Hippocrates's earlier work, an excess in yellow bile causes one to exhibit a choleric temperament. Those with a choleric temperament are described as passionate, ambitious, and bold. This understanding framed much of the medieval conception of human psychology and physiology, postulating that personality traits and behavior could be linked directly to the balance, or imbalance, of bodily fluids.Studies have shown that high levels of anger and negative emotional states like hostility can significantly increase the risk of developing cardiovascular conditions such as heart disease. Taking care of emotional health is critical to managing stress and reducing the likelihood of inflammation and related diseases.
